WEST PALM BEACH, FL, October 30, 2025 – AMG, a strategic partner to leading independent investment management firms globally, in partnership with its Affiliate GW&K Investment Management, announced the launch of the AMG GW&K Muni Income ETF (MUNX), which began trading on the New York Stock Exchange (NYSE) today.
MUNX is managed by GW&K’s seasoned municipal bond team: John B. Fox, CFA (Partner and Director of Fixed Income), Kara M. South, CFA (Partner, Municipal Bond Portfolio Manager), Martin R. Tourigny, CFA (Partner and Portfolio Manager), and Brian T. Moreland, CFA (Partner and Portfolio Manager). Together, they bring decades of experience and a deep understanding of the municipal bond market, underpinned by GW&K’s rigorous credit research and active portfolio management approach.
“Our team is excited to bring our municipal bond expertise to the active ETF market,” said Kara South, Portfolio Manager at GW&K Investment Management. “MUNX reflects our disciplined, research-driven approach and our commitment to helping investors achieve tax-exempt income through municipal investments.”
MUNX seeks to generate current income exempt from federal income tax, primarily through a diversified portfolio of investment-grade municipal bonds. The Fund leverages GW&K’s bottom-up, fundamental research and rigorous credit analysis to uncover opportunities across the municipal landscape. The team has the flexibility to invest in below-investment-grade securities while actively managing duration in response to interest rate shifts.
With more than $33 billion in municipal assets under management, GW&K is a market leader and pioneer in municipal bond investing, having managed such portfolios for clients since its founding in 1974. GW&K’s investment approach is active, flexible, and rooted in disciplined research to preserve and enhance principal and income. The firm offers a range of actively managed municipal solutions across open-end funds and separately managed accounts (SMAs)—providing U.S. wealth investors with high-quality municipal bond exposure tailored to meet clients’ individual investment goals and preferences.
“We are excited to collaborate with GW&K in broadening its municipal bond platform by offering clients access to a wider range of investment vehicles,” said Rachel E. Jacobs, Head of Client Solutions at AMG. “The launch of the AMG GW&K Muni Income ETF underscores our commitment to providing flexible solutions designed for today’s market environment and evolving client needs—including the growing demand for both actively managed ETFs and municipal bond strategies.”
